Female sex control: a third way

Females have an extra X chromosome as compared to males, and this can mean trouble – think of what happens when someone has an extra copy of any other chromosome, 21 being the most (in)famous! Dosage compensation is therefore essential, and there’s different ways of dealing with it. In humans, women inactivate one of their X chromosomes, while in the fruifly the opposite happens: males overactivate their only copy of X. The complex in charge of doing so is called MSL and male-specific-lethal-2 (msl2) is one of its subunits. Female flies must inhibit this gene in order to survive, and … Continue reading Female sex control: a third way

Listening to the language of neurones

Coming from the Rockefeller University in NY, Matthieu Louis leads the Sensory Systems and Behaviour group at the CRG, the only lab in Barcelona, and one of the few in Spain, investigating Drosophila neuroscience. His team comprises eight people with backgrounds in molecular biology, engineering and physics. Their aim is to correlate neural circuit function with behaviour using fruit fly larvae. “The Drosophila larva has a repertoire of complex behaviours and key cognitive functions. Yet its nervous system has 10 million neurones fewer than humans”, explains the physicist. The group tries to understand how odours are encoded by the olfactory … Continue reading Listening to the language of neurones

Her Majesty the Queen visits our research park

The March 2012 edition of the PRBB newspaper, El.lipse, a monthly bilingual newspaper, is now available. To download a PDF version please click here. You can see a multimedia version here. Her Majesty the Queen of Spain has visited the FPM at the PRBB this February. Also, find out about the core facilities coalition that supports research at the park. Matthieu Louis, from the Centre for Genomic regulation (CRG), tells us about his research into Drosophila neuroscience, and Anna Bigas (IMIM-Hospital del Mar Research Institute) explains her life as a scientist. Other news include the repositioning of drugs for rare diseases; improving the value … Continue reading Her Majesty the Queen visits our research park
